HIRAM E. FULLER, OF TAMA CITY, IOVVA-v IMPROVEMENT IN STEAM-COOKERS.

Specification forming part of Letters Patent No. 179,292., dated J une27,1876; application filed May 29, 1876.

To all whom it may concern Be it known that I, H. E. FULLER, of TamaCity, in the county of Tama and in the State of Iowa, have inventedcertain new and useful Improvements in Steanr-Gookers; and do herebydeclare that the following is afull, clear, and exact descriptionthereof, reference being had to the accompanying drawings, and to theletters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists in the construction and arrangementof a steamcooker, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a plan view of my cooker with a part of the lid broken off.Fig. 2 is a bottom view of the same with a part of the bottom brokenoff. Fig. 3 is a vertical section of the cooker.

A represents the bottom vessel or kettle in which the'water is containedfor generating steam. Above the same is a series of vessels, B U D,having suitable flanges under their bottoms, so as to fit within eachother, as shown. The first one, B, of these vessels is provided with acentral perforated pipe, B extending upward nearly to the top thereof.Within this perforated pipe is a tube, B extending above and below thesame, and held apart from the walls thereof by small arms a a,connecting the two together. The second vessel, C, is provided withsimilar tubes (3 and C of so much smaller diameter than the tubes B Bthat when the vessel 0 is placed upon the vessel B the upper end of thetube B will fit closely on the inside of the perforated tube 0 at thelower end, and the lower end of the tube U will be within the upper endof the tube B and suflicient space be left between themfor the passageof steam. In like manner other vessels may be added until the last or.top one, D, which has simply a central perforated tube, D ,.into thelower -end of which the upper end of the tube 0 tits closely. This topvessel is provided with a lid or cover, E.

As steam is generated in the bottom vessel or kettle A, the steam passesup between the two tubes B and B and through the perforations in thepipe B into the vessel B for steaming the food placed therein. The steamin this vessel cannot ascend to the next one, as the entrance is closedby the pipe B From the kettle A the steam also passes up through thetubes B and G into D and through the vperforations therein into the topvessel 1). It

also passes between the pipes B and (J into and through the perforationstherein into the vessel 0.

The steannit will be seen, in the various vessels is entirely confined,so that the odor from one vessel will not mingle with that of theothers.

In each vessel is placed a perforated false bottom, G, made convex onits upper side, and provided with feet (1 d, to hold it at a suitabledistance from the bottom of the vessel, thus leaving room in which thecondensed steam can collect and be away from the food cooking and keepthe food dry. The perforated bottom G is, on its upper side, providedwith knobs I) b, by means of which it is easily put in and taken out, asrequired.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patcnt,is

The combination of the vessel A, a series of vessels, B C D,havingiuterior flanges, as shown, perforated pipe B interior tube 13tubes 0 O of smaller diameter, central perforated tube D and the convexperforated false bottom Gr, all constructed substantially as and for thepurposes herein set forth.

In testimony that I claim the foregoing I have hereunto set my hand this9th day of May, 1876.
